Incorporating new problems and examples, as well as MATLAB material, this second edition gives clear descriptions of linear systems and uses mathematics not only to prove axiomatic theory, but also to ...

This Design Brief introduces a computationally efficient network that computes the derivative of a discrete time-domain (digital) sequence. While recursive differentiating networks exist, this article ...

Amplifying the small signals produced by sensors in a low-noise circuit is a very common but difficult problem. Designers will often use an operational amplifier (op amp) with bipolar inputs to ...
